For persons with long-standing and intractable symptoms of vertigo or imbalance that have not responded to treatment through the conventional medical channels, Dr. Epley offers the Comprehensive Vertigo Consultation (CVC). For this, he has assembled a set of vestibular tests designed to pinpoint the source of dysfunction in over 95% of cases of chronic vertigo and/or imbalance. Some of these tests are unique, available only at the Portland Otologic Clinic (POC).

Questions Regarding the
"Comprehensive Vertigo Consultation"

What do these 'unique' tests have to offer?

The 'unique' tests are designed to probe for abnormalities that the other tests don't detect. The Sound Evoked Destabilization Test probes for certain otolith organ abnormalities. The Omniax Positional Study analyzes complex semicircular canal abnormalities. The Labyrinthine Anesthesia Test localizes vestibular abnormalities and verifies their significance.

I’ve had vertigo and imbalance for several years following a minor automobile accident. A local specialist told me that because my ENG test was normal, an inner ear abnormality had been ruled out. Is that correct?

No! Much of the failure of mainstream medical care to properly diagnose and resolve chronic vertigo and imbalance problems is due to the common fallacy that "a normal ENG (Electronystagmogram) essentially rules out an inner ear disorder." Nothing could be further from the truth. In fact, the ENG can be normal in a number of common, treatable vertigo problems originating in the inner ear. No medical decision should be made on the basis of a normal ENG alone.

What can I expect from the Comprehensive Vertigo Consultation?

After a preliminary interview by our specially trained clinical associate, you will undergo an otoneurologic examination by Dr. Epley, and at least five of the following tests: AA, IMP, ENG, CDP, IRV, SED, VAT, ECOG, ABR, TCR, LAT.   (See below for an explanation of these abbreviations.) 

After initial testing is completed, you will meet with Dr. Epley and his nurse to review the test results. At this time, Dr. Epley will recommend treatment or possible further testing.

How long does the CVC take?

From 2 to 5 days, depending on the complexity.
